A-Rod matching Gehrig's 23 Grand Slams is a bit ho hum. I think anything ARod does is tarnished so its kind of like Bonds passing Aaron's all Time HR mark.. big deal.. It aggravates me a bit to even mention known juicers with Hall of Famers!!!
For what its worth, I think the ONLY unassailable mlb record is Cy Young's 511 wins. Think about it this way... A pitcher could win 20 games a year, 20 years in a row and he would still be 111 wins shy of Cy Young! CRAZY!
